ABSTRACT:
A system for automatically controlling the charging operation of an electronic flash in a photographic apparatus operates to enable the electronic flash to charge in response to readying the camera in anticipation to implementing a photographic exposure cycle and thereafter disabling the charging of the electronic flash as soon as the electronic flash reaches its full charge condition. The control system responds to the subsequent actuation of the camera to initiate a photographic exposure cycle to reenable the electronic flash to again become fully charged. After the electronic flash is fully charged, it is again disabled from further charging during the remainder of the photographic exposure cycle.
